ELASTIC WEBBING.

Specification of Letters Patent.

Patented Nov. 5.1912.-

. Application filed March 23, 1912. Serial No. 885,803.-

To all whom it may concern:

Be it known that I, WVALDEMAR Kors, a citizen of the United States of America, residing at the borough of Manhattan, city, county, and State of New York, have invented a new and useful Improvement in Elastic Webbing, of which the following'is a specification.

My present invention relates to an elastic webbing similar to that shown and described in .my application for Letters Patent, Serial No. 651,549, filed September 27, 1911, and Serial No. 652,164, filed September 30, 1911, that is to say, a webbing with elastic and cotton weft threads, where the stretch is across or at right-angles to the warp threads or length of the webbing and wherethere are marginal inelastic sewing sections running lengthwise of the webbing.

In the webbing of my presentv invention, the lengthwise'marginal inelastic or sewing sections are tubular and these may be of any desired width or thickness and the elastic filling or Weft at the return bends, or in other words, where it is doubled upon itself, lies wholly within the tubular inelastic or sewing sections or tubular pockets where these parts are protected from any frictional wear. These tubular inelastic margins, in addition to being employed as sewing sections, may be employed as pockets for stiffening devices, all of which is hereinafter more particularly described.

In the drawing, Figure 1 is an elevation of a short length ofelastic webbing according to my invention. Fig. 2 shows 'a length of such webbing connected as a gore in a piece of fabric and Fig. 3- is a cross section through Fig. 1 and in large size for clearness.

It will be realized that figures shown in the drawing are diagrammatic only and present as near as possible the actual way in which the warp and weft threads are woven.

Similar letters of reference in the several figures indicate the same parts.

a represents the elastic section through the central portion longitudinaily of the webbing, and 6 represents the elastic strands or elastic weft laid back and forth across the elastic section with the ends bent, or in other words, doubled upon itself.

0 and (l are the inelastic margins or sew- 5 ing sections lengthwise of the fabric and rand there are protected.

parallel with the warp threads and made tubular from slightly within the bent or returned ends of the elastic strands to the edges.

e in Fig. 2 represents a piece of fabric to which the length of webbing is connected as a gore.

The tubular margins or sewing sections are woven by using an additional cotton weft or filling thread, throughout. the width of the webbing, which when thrown across the lay of the loom in one direction binds substantially one half of the warp threads in said non-elastic section, and when traveling the reverse Wayjbinds the remaining half of the said sections.

It is, however, understood that I can make the tubular non-elastic sections in similar manner, as shown in Figs. 1 and 20f my application for Letters lgatent, Serial N 0. 651,550, filed Sept. 27th; 1911. That is, the use of a cotton weft thread or separate filling thread for each non-elastic section, each of which binds substantially one-half of the warp threads of one non-elastic section, when traveling across the lay of the loom in one direction, and binds the remaining half when traveling the reverse way.

I Fig. 3, on an exaggerated scale, illustrates fairly Well and clearly the re spective threads oi the warp and weft and shows the bent ends of the elastic strands or filling as coming within the tubular margins or pockets In Fig. 2, the elastic webbing is shown as inserted as a gore in a fabric strip and the edge of the fabric and theelastic webbing finished with an over-lock-stitch edge. These tubular edges may not only be employed as sewing sections, but in addition thereto may be employed as pockets for bone or other stifi'eners and for reinforcement strips, according to the use to which the webbing is to be put.

I claim as my invention:

1. A flat strip elastic fabric comprising a longitudinal elastic center and tubular marginal inelastic sections. 2. A flat strip elastic fabric comprising a longitudinal elastic center of elastic weft and tubular inelastic margins or sewing sections.

3. A flat strip elastic fabric comprising a longitudinal elastic filling or weft so as to stretch at right angles to the line of the warp threads and marginal tubular inelastic or sewing sections for securing the elastic fabric in position.

4. A flat strip elastic fabric comprising an elastic center of elastic weft and tubular inelastic margins which at the same time are adapted as sewing sections and for receiving stiffening devlces.

5. A flat strip elastic fabric comprising an elastic center of elastic weft running at right angles to the warp threads and the elastic weft laid back and forth through the elastic section with the ends bent or returned on itself and with tubular inelastic margins or sewing sections formed b additional cotton weft, the inner edges 0 which extend back of the returned ends of the elastic weft, whereby the elastic weft, at its returned ends, is within the tubular sections protected from external influence.

Signed by me this 18th day of March,

WALDEMAR KOPS.
